Rainproof vehicle rear view mirror

Abstract

The invention provides a rainproof vehicle rear view mirror which comprises a shell, a motor mounting plate, a motor, a nut, a lifting cap, a mirror face, a large screw and a small screw. The shell is a rectangle with edge angles being circular angles. The front face of the rectangle is inwards provided with a small hole, and the rear side of the rectangle is inwards provided with a large hole. The edges of the top faces and the side faces of the front hole and the rear hole are all provided with air holes which communicate through smooth air channels formed in the shell. The motor mounting plate is mounted on the innermost side of the rear hole of the shell through the large screw. The motor is mounted in front of the motor mounting plate through the small screw. An output shaft of the motor is machined into a threaded lead screw. The nut is mounted on the lifting cap through the small screw. The nut and the output shaft of the motor form a lead screw nut structure. The mirror surface is mounted on the rear side of the motor mounting plate. In rainy days, the motor drives the lifting cap to move inwards to enable air inlets to be exposed; and when an automobile travels forwards, airflow penetrates through the air channels to form an air layer on the surface layer of the mirror surface to hinder raindrops from being adhered to the mirror surface, the mirror surface is kept clear, and road traffic accidents in rainy days are effectively reduced and prevented.

Description

technical field [0001] The invention relates to a vehicle component, in particular to a rainproof vehicle rearview mirror. Background technique [0002] Nowadays, the construction of transportation facilities is more and more developed, but it still cannot meet the rapid expansion of the number of cars. According to statistics from the Traffic Management Bureau of the Ministry of Public Security, as of the end of June 2016, the number of motor vehicles in the country has reached 285 million, of which the number of cars has reached 184 million; of which 184 million are cars; 296 million drivers. What follows is the increasing number of traffic accidents. According to statistics, on average, one person is killed by the wheel every 5 minutes, and every 1 minute is disabled due to traffic accidents. The economic losses caused by traffic accidents amount to tens of billions of yuan every year. [0003] Among the factors that lead to frequent traffic accidents, bad weather is a...

Problems solved by technology

[0005] Therefore, in order to solve the problem of rainwater adhering to the vehicle rearview mirror, the present invention provides a kind of rain-proof vehicle rearview mirror, which utilizes the gas flow generated by the forward movement of the vehicle to form a gas protective layer near the mirror surface of the rearview mirror. The raindrops that were supposed to land on the mirror surface drift away with the air flow, and the mirror surface will still be covered with raindrops after parking, but once the vehicle moves forward, the raindrops will be dried immediately, and the mirror surface will become clean immediately
